The ODROID-C2 has many advantages over the
Raspberry Pi 2.
The processor is an S905 ARM 64-bit 1.5 GHz quad core with 2 GByte DDR3 RAM,
Gigabit Ethernet and IR receiver. The size of this computer is still only 85 mm x 56 mm
with a weight of 40 g, and offers silent operation, 2~5W average power usage, and instant
portability, since it fits in a shirt pocket. One powerful feature of the ODROID-C2 is an SD 3.01
standard compatible UHS-1 MicroSD card, as well as the faster eMMC module.
Insert the MicroSD card into the slot, connect a monitor, a keyboard, a mouse, Ethernet and power
cable, and that's all you need to do to use the ODROID-C2!
Browse the web, play games, run office programs, edit photos, develop software, and watch videos right away.
The ODROID-C2 also has a 40+7-pin GPIO header to make a physical interface between the board and the
outside world. The 40+7-pin interface headers include PWM, I2C, I2S, UART, ADC and GPIO function.
The IR receiver and ADC features on the ODROID-C2 offer many options for building great DIY projects.

SD/eMMC PERFORMANCE
The C2 can boot from a MicroSD card or an
eMMC module. The MicroSD interface supports the higher
performance UHS-1 mode as well. File access of a 512 MB file (read/write) on two different
storage options shows distinct performance differences.
The eMMC 5.0 storage is ~7x faster than the MicroSD Class-10 card in read tests. The MicroSD
UHS-1 card is ~2x faster than the MicroSD Class-10 card in read tests. The MicroSD UHS-1 card
provides a great low-cost option for many applications!

ETHERNET PERFORMANCE
The C2 has an on-board Gigabit Ethernet controller. The bi-directional streaming speed was
measured at ~900Mbps. Thanks to the doubled Tx buffer in the S905, the upload speed is twice
faster than C1.
